MGA ++ V1.06 Safeguards Software
MGA++ is a suite of three software programs (MGA, U235 and MGAHI) for analysis of Actinide spectra acquired by germanium detectors. MGA++ is the result of years of continuing development at Lawrence Livermore National Laboratory. 1 The original MGA code was developed to determine plutonium isotopic abundances for gamma-ray data taken with germanium detectors. MGA-B32 consists of 1) an upgraded version of the original MGA code, which relies on the 100-keV region; 2) U235, a uranium isotopic analysis code that uses gamma rays less than 300 keV; and 3) MGAHI, a plutonium isotopic analysis code that uses the 200 keV–1 MeV energy region. The codes analyze gamma-ray data collected with a HPGe detector.

FRAM Software
- FRAM analyzes Pu, and a wide variety of heterogeneous samples containing Pu, Am, U, and other nuclides including 242Pu
- Operates with a single HPGe or CdTe radiation detector
- No calibration standards necessary
- Works with shielded samples
- Select from a large number of supplied sample/geometry conditions or add more types
- Decay Correction for Isotopic fractions
- Significant enhancements over previous versions
FRAM analyzes the gamma-ray spectrum taken with a germanium radiation detector, of plutonium-bearing, uranium-bearing, or mixed items and quantifies the distribution of plutonium or uranium isotopes, 241Americium, and other transuranic isotopes (including uranium in mixed uranium-plutonium oxides) that contribute measurable gamma rays to the spectrum. These can also be quantified relative to plutonium. FRAM analyzes spectra from items containing only uranium, and quantifies the uranium isotopic distribution. These measurements are performed on samples of arbitrary size, geometry, and physical and chemical composition.
